Yeah, so it relies a lot on I suppose gravitational potential energy.

对，我认为主要借助于重力势能。

This stores the energy by giving the water extra gravitational potential energy.

这通过给水额外的重力势能来储存能量。

This rhythm repeats throughout the ride, acting out the coaster engineer’s choreographed dance of gravitational energy.

这种节奏在整个旅程中不断重复，演绎着过山车工程师精心编排的重力能量之舞。

One common type of potential energy is gravitational potential energy

最常见的势能类型之一 它是引力势能。

Unlike cars or transit trains, most coasters are propelled around their tracks almost entirely by gravitational energy.

与汽车或公交火车不同，大多数过山车几乎完全由重力能量围绕其轨道推动。

If I hold this book a meter above the ground, we'd say that it has gravitational potential energy.

如果你把这本书放在一米以上的高度 地球，我们说有引力势能。

Once the book hits the ground, though, we'd say that its gravitational potential energy

但书一落地， 我们说它的引力势能为零。

If we move them further away, or opposite the direction of the gravitational force, we increase their gravitational potential energy.

如果我们将它们移得更远，或者与重力方向相反，我们就会增加它们的重力势能。

It transformed black holes from an end point into a kind of cosmic forge, where the intense gravitational energy could create particles and, potentially, new universes.

它将黑洞从一个终点变成了一种宇宙熔炉，在那里强烈的引力能可以创造粒子，并有可能创造新的宇宙。

Now twice zero is also zero. Thus the universe can double the amount of positive matter energy and also double the negative gravitational energy without violation of the conservation of energy.

现在两次零也是零。因此，在不违反能量守恒的情况下，宇宙可以使正物质能量加倍，也可以使负引力能量加倍。

Moving it to a higher shelf would mean it has gravitational potential energy relative to that lower shelf, or relative to the floor if we want to use that as our comparison instead.

将其移至较高的架子意味着它相对于较低的架子具有重力势能，或者如果我们想用它作为比较的话，则相对于地板具有重力势能。

Calculating gravitational potential energy is easy enough
